Title: Poly(phenylene alkylene)-based lonomers

Abstract

A composition and method of forming a composition including a compound including a poly(phenylene) backbone represented by the following formula: ##STR00001## wherein each of R.sub.1, R.sub.2 and R.sub.3 may be the same or different and is H or an unsubstituted or inertly-substituted aromatic moiety; wherein Ar.sub.1 is an unsubstituted or inertly-substituted aromatic moiety; wherein R.sub.4 is an alkylene, perfluoroalkyl, polyethylene glycol, or polypropylene glycol moiety; wherein each of R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.10 and R.sub.11 is H or a monovalent hydrocarbon group including two to 18 carbon atoms, with the proviso that each R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.10 and R.sub.11 cannot be H; and wherein each of Y.sub.6, Y.sub.7, Y.sub.8, Y.sub.9, Y.sub.10 and Y.sub.11 may be the same or different and is H or a functional group are disclosed. The composition can be used as anion-exchange membranes and as an electrode binder material in anion exchange membrane fuel cells.

  • A poly(phenylene) compound of copolymers that can be prepared with either random or multiblock structures where a first polymer has a repeat unit with a structure of four sequentially connected phenyl rings with a total of 2 pendant phenyl groups and 4 pendant tolyl groups and the second polymer has a repeat unit with a structure of four sequentially connected phenyl rings with a total of 6 pendant phenyl groups. The second polymer has chemical groups attached to some of the pendant phenyl groups selected from CH.sub.3, CH.sub.2Br, and CH.sub.2N(CH.sub.3).sub.3Br groups. When at least one group is CH.sub.2N(CH.sub.3).sub.3Br, the materialmore » functions as an anion exchange membrane.« less
  • Energy-curable compositions which can be cured in the presence of air by exposure to actinic radiation contain at least one unsaturated urethane oligomer. The oligomer comprises the reaction product of at least one poly(alkylene oxide) polyol, at least one polyisocyanate, and at least one unsaturated active hydrogen-containing compound.
  • An epoxy-crosslinked sulfonated poly(phenylene) copolymer composition used as proton exchange membranes, methods of making the same, and their use as proton exchange membranes (PEM) in hydrogen fuel cells, direct methanol fuel cell, in electrode casting solutions and electrodes, and in sulfur dioxide electrolyzers. These improved membranes are tougher, have higher temperature capability, and lower SO.sub.2 crossover rates.
  • Improved multi-block sulfonated poly(phenylene) copolymer compositions, methods of making the same, and their use as proton exchange membranes (PEM) in hydrogen fuel cells, direct methanol fuel cells, in electrode casting solutions and electrodes. The multi-block architecture has defined, controllable hydrophobic and hydrophilic segments. These improved membranes have better ion transport (proton conductivity) and water swelling properties.
  • A composition and an anion exchange membranes including a composition and a method of forming a composition including a compound including a poly(phenylene) backbone represented by the following formula: ##STR00001## wherein each of R.sub.1, R.sub.2 and R.sub.3 may be the same or different and is H or an unsubstituted or inertly-substituted aromatic moiety; wherein each of Ar.sub.1 and Ar.sub.2 may be the same or different and is an unsubstituted or inertly-substituted aromatic moiety; wherein each of R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.10 and R.sub.11 is H or a monovalent hydrocarbon group including two to 18 carbon atoms, with the proviso thatmore » each R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.10 and R.sub.11 cannot be H; and wherein each of Y.sub.6, Y.sub.7, Y.sub.8, Y.sub.9, Y.sub.10 and Y.sub.11 may be the same or different and is H or a functional group.« less
